APPARATUS FOR PURIFYING GAS.

SPECIFICATION forming part of Letters Patent No. 769,713, datedSeptember 13, 1904.

Application filed September 28, 1901. Serial No- 76,305. (No model.)

To (LU whmn it ntay concern.-

Be it known that I, J OSEPH ETIENNE PRE- GARDIEN, a subject of theEmperor of Germany, residing at Kalk, Rhineland, Germany, have inventedcertain new and useful I mprovements in Gas-PurifyingApparatus, setforth in the following specification.

In the apparatuses forpurifying gas already known, in which singlecondensing-chambers are connected by means of pipes to form a continuousseries, there is the drawback that for cleaning out single chambers thewhole series must be put out of use and the manufacture therebyinterrupted.

The present invention is for the purpose of enabling singlecondensing-chambers to be cleaned without interrupting the process. Thisis effected by inserting in each pipe, connecting twocondensing-chambers with each other, a double and single plug, whichallows a communication being made between one chamber and the next orshutting off this latter and making connection with a pipe discharginginto the main connectingpipe above the plug.

1n the accompanying drawings, Figures 1 to 3 illustrate diagrammaticallyone constructional form of the invention. Fig. 4 shows another form ofconstruction.

The special construction of my invention may be more clearly followed byreference to the characters on the drawings.

The suitably-cooled condensing-chambers 1 2 3 4 5 are connected in aseries by means of outlet-pipes 7), b 6 I), and 5 which are secured inthe upper end of each chamber and are connected with a main gas-carryingpipe (I. Extending into each chamber are pipes a (f, (2 (1 and (5, whichare connected to the main supply-pipe (Z for conducting the gases intothe condensers, wherein are separated the impurities in the gases.

Upon each of the inlet and outlet pipes, just above the top of thecondensing-chambers, are dish-shaped extensions 0 to 0", into which arefitted pipe-sections g g, which are greater in cross-section than theends of the inlet and outlet pipes and adapted to permit of the movementtherein of valves h 74/. These pipe-sections g g are hermetically sealedin said extensions or sealing-grooves c to 0 and main supply-pipe (Zconnects through them with inlet-pipes a to ai upon the plugs it itbeing lifted out of their seats. At the upper end of the pipe-sectionsare inserted pipes f, whose ends are adapted to seat valves 7b. Thesepipes f are connected by pipes (Z to (Z to the pipe-sections g of theoutlet-pipes I) to The valves it h are so arranged by means of chains ii, which are wound around drums a to a, as to be lifted upon therotation of said drums ofl' their seats upon the upper-ends of the inletand outlet pipes, which extend into the pipe-sections r g and to closethe pipes f, while at the same time opening the inlet and outlet pipesleading to the condensers 1 to 5. By this means gas from themainsupply-pipe is admitted to the condensers, or by seating the valves uponthe inlet and outlet pipes of one or more condensers communication tosaid condensers may be closed and the gas flow by pipes (Z to (Z to theother condensing-chambers. In this manner any one of the series ofcondensing-chambers may be cut out without retarding the process ofpuriiication.

In Fig. 4 is shown a slightly-modified structure wherein the pipes a toa arejupon the outside of the condensing-chambers, the gases havingfirst to pass through cross-pipe a: when the plug-valves h are in theposition shown before being carried through the condensingchamber andthrough the outlet-pipes to the next of the series. j is a receptaclecontaining a liquid to form a seal with J and a.

Having now particularly described and ascertained the nature of my saidinvention and in what manner the same is to be performed, I declare thatwhat I claim is In a gas-purifying apparatus, the combination of aseries of condensing-chambers, inlet-pipes communicating therewith, aseries of outlet-pipes connected to said chambers, inclined pipescommunicating with said inlet and outlet pipes, a series of by-passpipes connecting said outlet and inlet pipes, a plugvalve, arranged insaid outlet and inlet pipes of each condensing-chamber, and means tooperate the valves simultaneously, to cut out or in one or more of saidchambers of the series, substantially as described.

In Witness whereof lhave hereunto set my hand in presence of twowltnesses.
